orbitals with the same energy level

Question 22

Valence bond theory

Answer 22

treats every bond as the sharing of electron density between two atoms as a result of the constructive interference of their atomic orbitals

Molecular orbital theory

Answer 24

uses a mathematical methods called the linear combination of atomic orbitals to form molecular orbitals
